产品概述 返回TOP
The CXSU63198 is a current mode boost DC-DC converter,Its PWM circuitry
with built-in 0.25Ω power MOSFET make this regulator highly power efficient.
The internal compensation network also minimizes as much as 6 external
component counts. The non-inverting input of error amplifier connects to a
0.6V precision reference voltage and internal soft-start function can reduce
the inrush current.The CXSU63198 is available in the SOT23-6L package and
provides space-saving PCB for the application fields.CXSU63198为一颗CC
(恒流)模式的PWM升压IC,适用于锂电池(3~4.2V)输出5V,1A的移动电源应用。
CXSU63198封装为SOT23-6,工作频率为1MHZ,可以搭配3.3uh
